What story does the novel The Barber tell? Tell me about the plot and the fate of the main characters.

I don't know if it's the barber of Xiangxi Ghost King. This book tells the story of a dying boy. His name is Yang Chuan, alias Chuanzi. When he was dying, Liao Fan, a barber who shaved pubic hair, was invited at home, and then Liao Fan saved his life. Chuanzi regarded Liao Fan as his father. When he grew up, Chuanzi formally worshipped Liao Fan as a teacher and studied Feng Shui and Taoism. During this period, I met and adopted a Yin dog and a rat demon. They have experienced many adventures of exorcising ghosts and corpse. Finally, Liao Fan is the king of worms in Long Live Mountain, the most powerful mage. Chuanzi is actually the reincarnation of General Tian Fei. Liao Fan has been using Chuanzi to awaken the memory of General Tian Fei and learn his skills. Finally, General Tian Fei didn't want to be used any more, so he went far alone and finished the whole movie.
